A method and system for chemical transportation, storage, and dispensation, which provides a base with ISO mounts for enabling a ISO tank, van container, screw conveyor, or the like to be carried thereon. The base accommodates either or both of roll off or hooklift hoist technologies to allow easy loading and unloading. A first end of the base is carried by one or more rollers, and the underside is structured to allow rolling of the base on the bed or rack of the transport vehicle. After unloading the base with its ISO cargo, the transport vehicle leaves the well site and is free to retrieve another ISO tank or container as appropriate, thereby lowering the tractor-trailer capital requirements to support fracturing operations. Weigh scales allow the weight of the ISO container to be determined to allow the operator to monitor the inventory of chemicals as they are used.

A mini-container for inter-modal shipping includes panels forming a pair of oppositely disposed side walls, a front wall, a back wall opposite to said front wall, a floor, and a roof. The side, front and back walls may releasably lock to one another to form an enclosure and unlock from one another. The panels are positionable between an erected-for-use configuration and a collapsed storage configuration. In the storage configuration, the side, front and back panels are stacked lying flat to form a stack of the panels laying on the base. The stack of panels is overlaid with the roof. The erected mini-containers are sized for space efficient loading of an inter-modal mobile transport conveyor such as an automobile carrier, train, ship or plane. In their storage configuration the mini-containers may be carried on the mobile transport conveyors for later use carrying cargo and may be carried in a stack simultaneously with mini-containers carrying cargo. The mini-containers may be sized so as to enclose at least two standard-sized pallets or at least three standard-sized boxes positioned side-by-side and adjacent the base of the mini-container.

The present invention is a system for transporting and storing construction materials for a job site using a tractor trailer having a plurality of openings, a container having a frame carrying support feet for being received into the tractor trailer openings, a plurality of attachment points carried by the frame on the floor of the interior of the container, a plurality of shelves carried by the interior of the container; and a door carried by the container having a lock.

A tank assembly for a helicopter is provided. The tank assembly includes a retractable tank for storing liquid or other substances. The retractable tank includes an upper frame structure. The tank assembly further includes an attachment mechanism attached to the upper frame structure and configured to engage a main rotor transmission of the helicopter to suspend therefrom. A helicopter including a fuselage, a main rotor transmission, and a tank assembly is also provided.

A bulk material container can include a body, having a plurality of side walls, a bottom, a cavity, and an opening, and a first engagement element. The plurality of side walls are coupled to the bottom, and the cavity, which is configured to receive a bulk material, is formed within the plurality of side walls and above the bottom. The opening is formed by the plurality of side walls spatially opposite of the bottom and is configured to discharge the bulk material when the container is at least partially inverted. The first engagement element can be configured to receive one or more prongs of a transportation device or a bulk material unloading device. In some embodiments, the container may also include a second engagement element and/or a third engagement element, for example with the first, second, and/or third engagement elements differing from each other.

A collapsible container that includes a base, a first side panel hingedly attached to the base, a second side panel hingedly attached to the base, a first end panel hingedly attached to the base, with the first end panel including a door, and a second end panel hingedly attached to the base. The collapsible container can further include a top cover. The collapsible container is configured to be positioned in a collapsed position and an assembled position. In an assembled position, the collapsible container is configured to hold items during a domestic or international move.

Described herein are units for transportation of cargo, and methods of using them. In some embodiments, the units are collapsible, stackable cargo units. In some embodiments, the cargo units include a generally rectangular base having a front, a rear and two sides, with forklift slots on its front, rear and each side. The cargo units may further include front and rear walls extending upward from the base. The cargo units may further include first and second side walls extending upward from the base between the front and rear walls. The first side wall may have a length greater than the second side wall. The cargo units may further include an integrated lid hingedly attached to one or more of the front, rear, and side walls.

An equipment transport bag assembly is operable to handle equipment having a lifting element. The bag assembly includes a bag and an equipment-handling assembly. The bag defines an interior configured to at least in part receive the equipment therein. The equipment-handling assembly includes a strap unit. The strap unit includes a strap attached relative to the bag. The strap defines a strap opening configured to receive the lifting element. The bag defines a bag opening configured to receive the lifting element. The strap opening and the bag opening are at least in part aligned relative to one another to facilitate contemporaneous extension of the lifting element through the strap and the bag.
